yah that makes sense....now that i know what it is im just not gonna worry about it bc next week my 406 is going in and i have a carter for it but i will be sure to check the pressure, dont think ill have any problems bc it ran great in the last car it was in but better safe than sorry. should i have anymore than 4.5 psi. for the 3X2 setup since there is a fuel rail and 3 bowls instead of only 2?
